Gamma rays are a type of electromagnetic radiation that are associated with the decay of atomic nuclei or other high-energy events. Synonyms for gamma ray include gamma radiation, gamma light, gamma photon, and gamma particle. Gamma radiation is the most commonly-used synonym, and is often used interchangeably with gamma ray. Gamma photons and gamma particles are also used to describe gamma rays, especially in scientific contexts where precision in language is important. Gamma light is a less-common synonym, but is still occasionally used to describe gamma radiation in some contexts. Regardless of the terminology used, gamma rays are a powerful type of radiation that is important in a variety of fields, including medicine, engineering, and nuclear physics.
